  • Applications

    1-Undecene, 11,11-bis((3,7-dimethyl-6-octenyl)oxy)-, CAS 67785-67-5, is typically regarded as a specialty polymer building block and functional material, capable of acting as a monomer or crosslinking additive in coatings, resins, adhesives, and related polymer systems; its two ether-bound terpenoid-like substituents give it a bulky hydrophobic character and potential use as a fragrance ingredient or fixative in perfumery and cosmetics; in cosmetic and personal care formulations, it may serve as a fragrance-related constituent or a solvent adjunct; in household products and cleaners, it could contribute to fragrance profiles and overall sensory attributes; final applications are subject to local regulations and formulation limits.
